Describe how the interaction of radiation with matter produces radiation that is characteristic of the matter in which the interaction took place.
Homework Answers
Light is supposed to travel in waves, so we can explain interference , diffraction etc. Black body radiation, photoelectric effect can be explained if it has a particle character. Particle is localised in space while wave is spread out in space.
All material particles such as electron , photon have both wave as well as particle chatacter is called matter.
Chemical property of matter - how a substance interacts with another substance.
When X-rays are directed into an object , some of the photons interact with the particles of the matter & their energy can be absorbed or emitted. Other photons travel completely through the object without interacting with the particle.
Transmission of photons through a material depends on energy .

What is meant by matter-radiation crossover? The conversion of matter into radiation by E = mc^2. The conversion of radiation into mass by E = mc^2. The time in the early universe when the radiation density had decreased relative to the matter density until they were equal.

In gene interaction, genes at different loci contribute to the determination of a single phenotypic characteristic. How does gene interaction differ from dominance? In your answer consider: Do genes interact or do gene products interact? How can the different levels of interaction be expressed-molecular, cellular and organismal? Include examples to gene interactions that produce novel phenotypes.
